We offer you the redesigned workhorse lens from Canon- EF 24-70mm f/2.8L II USM Zoom Lens. When you rent this exceptional piece of equipment, the boost in its optical performance becomes apparent when you compare to its elder brethren. Canon ups the ante for optical performance for a professional standard zoom lens. It has one Super UD lens element and two UD lens elements that minimize chromatic aberration in the periphery at wide-angle, as well as reducing colour blurring around the edges of the subject. In addition, two types of aspherical lenses are combined to help reduce spherical aberration over the entire image area, as well as through the full zoom range. Optimized lens coatings help ensure exceptional colour balance while minimizing ghosting.
